Let’s keep this simple:
Every time merit pay has been tried in schools, it has failed.
Belief in merit pay reminds me of Linus in the pumpkin patch. It doesn’t matter that the Great Pumpkin disappoints him year after year: he insists on believing. He can’t adjust his view of the world based on facts; the world must adjust to him.
So I’ve given up trying to change people’s minds on this. Either you are open to the truth, or you’re not. And the truth is, merit pay will never, ever help student achievement.
But don’t listen to me: (trust me, this clip is worth it)
